Calculate the LCM of 123,465,121,918

Given numbers are 123,465,121,918

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 123,465,121,918 is 705900690.

Find LCM of 123,465,121,918 with Prime Factorization


3 123, 465, 121, 918
41, 155, 121, 306

Multiply the prime numbers at the bottom and the left side.

3 x 41 x 155 x 121 x 306 = 705900690

Therefore, the lowest common multiple of 123,465,121,918 is 705900690.

LCM Formula to Find Lowest Common Multiple of 123,465,121,918

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

123 x 465 x 121 x 918 = 6353106210

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

123 : 1, 3, 41, 123

465 : 1, 3, 5, 15, 31, 93, 155, 465

121 : 1, 11, 121

918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 123,465,121,918, is 1.

Now, the common factors can be found like this.

123:3x 41

465:3x 5x 31

121:11x 11

918:2x 3x 3x 3x 17

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 3 = 9

Therefore, the value for common factors is 9.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 6353106210/(1x9)

LCM = 6353106210/9

LCM = 705900690

Thus, we can understand that the LCM of 123,465,121,918 is 705900690.
